Good start, but there's definitely some changes necessary here.

First of all: Get rid of Alexandria's Genesis. It's not real. So, no enhanced sight or purple eyes.

Secondly, there's no way in Hell a troupe of different species would group together under the control of a Djinn just to fuck over one family in particular. First of all, Vampires only really travel in packs of their own kind, so it's easier to get food that way; Werewolves are mindless animals during a full moon and total lone wolves, and in human form, are totally useless, and probably don't even know about their condition in the first place. From what I can gather from Crocottas, they seem to be pretty rare, and judging by the way they live and feed, I can't see it joining a gang of supes. Likewise with an Arachne. 
Just change it to seven Djinn - it's canon that they do have families, and will return for revenge, so that's fine.

Thirdly, this Angel-Demon hybrid. I'm guessing this is another person with another character, but I'll just save you the trouble with a big ol' Hell No. It's not possible.

Make those changes, and you're good to go.

EDIT: From what my research gathers, the Equus Bass prototype was released in 2014, and isn't even available to be purchased until 2016. This is set in 2009 - therefore, you'll have to pick a different car. 
Further studies into the guns: 
From what I can gather of the sniper rifle - a Remington MSR - although produced in 2009, it hasn't become available to purchase by the public (I.E civilians) until this year, from what I've read. So, different sniper, please.
Triple barrel shotgun - If you want one, give me a picture of one that isn't from Gears Of War.
Falconeer, Bloodrunner, and Claw and Fang, appear to be custom made guns. I can't find a production date for them, and there's also the issue of the price. Custom made guns do not come at a small price - and I can't see any family of hunters being able to afford four of them on top of the specialist weapons they already have. Especially because they appear to have been modified to look flashy and has blades attached; and that doesn't provide much of an advantage to the gun. Not worth what the cost would be anyways.
There's nothing wrong with normal guns - either pick some, or give me a realistic explanation as to why these hunters would throw money on something for the aesthetic of it.
